In https://online-go.com/game/view/22332155 what is a response to the fifth move? It seems weak to me, but I haven’t been able to figure out a good response.
You actually played the best response. See https://senseis.xmp.net/?EvenAMoronConnectsAgainstAPeep. The issue was with your follow ups. Try move 10 at D7 or even B8 (check my variations). Also try move 12 at C3, as the site AI suggests.
